IMPROVEMENT IN DOOR-CHECKS.

Specification forming part of Letters Patent No. 140,139, dated June 24,1873; application filed August 10, 1872.

To all whom it may concern:

Be it known that we, JOSEPH P. ISRAEL and DANIEL W. MOLANE, of Oil Oity,Venango county, Pennsylvania, have invented certain Improvements inBase-Knob for Doors,

Windows, &c.; and we do hereby declare that.

the following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon making a part of this specification.

The object of our invention is to provide a cheap, durable, andeffectual door check and catch.

This check may be made of any suitable materialas cast or malleableiron-ornamental or plain.

In the drawing, A is the bumper, which is fastened to the base-board orwall securely, and serves to keep the door a sufficient distance fromthe wall to prevent the key and knob from injuring the wall. This bumperis provided with two'lugs on the upper part of it, as shown in thedrawing, for a purpose hereinafter described. B is nothing more than aproperly-shaped lever, with a latch on one end and a button or knob onthe other, being so formed that the latch end is the heaviest. E is asmall plate or escutcheon, which covers an orifice in the door.

The practical operation of this door-check is as follows: The bumper Aand the latch or lever B are joined together with a rivet or pin,allowing the lever free play. The bumper is then fastened to thebase-board or wall. An orifice is then made in the door at the properplace and the escutcheon E placed over it. The lever B, having a beveledlatchhead, when it is struck by the lower edge of the orifice in theescutcheon E will be raised up, and,as soon as the latch passes insidethe escutcheon, the lever drops by its own weight and holds the dooruntil it is relieved by pressing on the other or knob end of the lever.

In the drawing the edge of the door is broken away to show the operationof the latch.

What we claim, and desire to secure by Letters Patent, is-

The combination of the bumper with a weighted latch-lever pivoted inlugs thereon, and furnished with an upwardly-projecting short arm andthe escutcheon on the door, all substantially as described. I

JOSEPH P. ISRAEL. DANIEL W. MoLANE.
